If I have multiple matlab windows in a tag and I maximize one of them, I can switch between the windows, and they have focus in whe wibox tasklist, but they don't have the border around them that focused windows usually have.
This was with two Matlab windows. If I have one Matlab window and another window (urxvt for instance) in a tag and I maximize one of them, I can switch between them, and they will change focus, but the Matlab window will always stay in the background, hidden behind the urxtv window...

Opened two freemind instances. Maximized one of them. When switching between those, everything works as expected. This is still with git master on debian, so what I said in FS#971 applies here as well.

Ok, so this is (again) a java bug. The big difference between the two is that git/master is a reparenting WM. Java is known to be terribly broken on non-reparenting WMs (which is what the wmname hack works around). The input handling stuff should be identical between the two.
